An SWL is a hyperlink on Wikipedia that allows the editor to explicitly specify the type of relationship between the concept described on the page being edited and the concept that is being linked to (http://en.wikipedia.org/wiki/Template:SWL). These SWLs are implemented using MediaWiki templates.(...)any programmer can now write computer programs to parse Wikipedia content for SWLs and import them into third-party tools (e.g. triplestores, etc.)
